Question: Four factors are thought to possibly influence the taste of
Four factors are thought to possibly influence the taste of a soft-drink beverage: type of sweetener (A), ratio of syrup to water (B), carbonation level (C), and temperature (D). Each factor can be run at two levels, producing a 24 design. At each run in the design, samples of the beverage are given to a test panel consisting of 20 people. Each tester assigns a point score from 1 to 10 to the beverage. Total score is the response variable, and the objective is to find a formulation that maximized total score. Two replicates of this design are run, and the results are shown in Table 8E.3. Analyze the data and draw conclusions.
Answer to relevant QuestionsConsider the experiment in Exercise 8.4. Plot the residuals against the levels of factors A, B, C, and D. Also construct a normal probability plot of the residuals. Comment on these plots. In exercise An electronic component in a dental x-ray system has an exponential time to failure distribution with. What are the mean and variance of the time to failure? What is the reliability at 30,000 hours? Twenty observations on the time to failure of a system are as follows: 1054, 320, 682, 1440, 1085, 938, 871, 471, 1053, 1103, 780, 665, 1218, 659, 393, 913, 566, 439, 533, and 813. Is the Weibull distribution a reasonable ...A simple series system in shown in the accompanying figure. The lifetime of each component is exponentially distributed and the for each component is shown in the figure. Assuming that the components operate ...Consider the system shown in the accompanying figure. The reliability of each component is provided in the figure. Assuming that the components operate independently, calculate the system reliability.
